Refactor the "find pci device" function to return a pointer to

some of the tests to reduce the indent level of the code. Pass
the struct comedi_devconfig pointer to the function instead of

are meant to iterate over, and write, all the data[] passed from

Reverse the logic of the test against the cached value so that

Make the logic of the dac write a bit clearer by create a local

value to write and setting the enable bits before doing the outw()
calls. Add a comment just to make sure it's clear.
Also, add a comment about the 'return 1;'. This should be

The NLMSG_PUT() macro contains a hidden goto that jumps to the

jumping to the nlmsg_failure label leaks the memory allocated for it.
